Just-Fit Ball Reducer JFR series
A flange-type Ball Reducer with a thin output section.
Its dedicated integrated crossed roller bearing in the output shaft enables the machine to handle high loads despite its low profile.
This model is 30% to 50% thinner than the conventional Ball Reducer.

Highlights
Thin Design
Its output shaft support uses a thin crossed roller bearing to achieve a thin profile and meet the design’s space-saving requirements.
Zero-Backlash
Uses a steel ball in the deceleration mechanism instead of a gear. Eliminates backlash and enables prevision feeding and high-precision positioning through constant rolling contact via preload.
Compact & Simple
Uses a steel ball in the deceleration mechanism instead of a gear. Eliminates backlash and enables prevision feeding and high-precision positioning through constant rolling contact via preload.
Motor Attachment Standardization
The JFR Series has standardized motor attachments for servo motors of various manufacturers, allowing the motor to be immediately installed after purchase.
Maintenance-free
Its grease-filled reducer can be used without lubrication for its entire rated life. Also has no mounting position restrictions.
High Efficiency
Its transmission mechanism achieves a high-efficiency drive using a large number of steel balls.
